About Dan Castellaneta:
Daniel Louis Castellaneta is an American actor, voice actor, comedian and screenwriter. Noted for his long-running role as Homer Simpson on the animated television series The Simpsons, he voices many other characters on the show, including Abraham "Grampa" Simpson, Barney Gumble, Krusty the Clown, Sideshow Mel, Groundskeeper Willie, Mayor Quimby and Hans Moleman.
The humor is essentially dark for a cartoon and sophisticated. But at the same time, being a cartoon gives the writers more freedom than in a normal sitcom. It always pushes the line that, despite human failings, the Simpsons are really decent people...Dan Castellaneta
One of my favorite episodes was the one in which Homer grew hair. That was a very unique episode, since there was a gay secretary, but that wasn't even the issue of the show-the issue was Homer's image changing because he had hair.Dan Castellaneta
